レートの使用寿命は短くなり得る。According to Finnish Patent Application No. 920937, the image plate is placed in a cover as described above during X-ray irradiation. In this regard, the handling and scanning of the plate can be problematic due to scratches on the plastic film on the image surface of the plate or fingerprints on the image surface that can appear in the resulting image. Occurs. In addition to the image plane, the edges of the plate are easily damaged and damaged. In practice, the edges of the plate are protected by a coated plastic film, but this has been found to be insufficient protection. If the edge breaks, RIM material inside the plate, such as a toxic barium compound, may appear and be dangerous to the patient and the person handling the plate. The unprotected RIM material is not resistant to sterilization, for example with ethanol, in which case the entire plate is destroyed. Such wear and tear problems can reduce the useful life of the image plate.

像の面積を顕著に減少させることもよい。The protective frame according to the present invention serves as an impact-resistant cover for an easily damaged edge portion of the image plate. Furthermore, according to the protection frame, since it protrudes from the image plane,
Wear and abrasion due to scratching of the surface are effectively prevented, and thus deterioration of image quality due to the abrasion is prevented. In addition, the protruding frame is easy to grasp, and disadvantageous fingerprints rarely remain on the image surface. Furthermore, since the frame is relatively small, the outside dimensions of the image plate may not be significantly increased, and the image plane and the area of the resulting image may be significantly reduced.
